Teleport Station

Teleport Stations are a type of station in Metroid: Samus Returns, implicitly built by the Chozo on SR388. They transport Samus to any other that she has already found, allowing her to quickly transport herself between the areas of SR388, as at least one is present in all of these areas.

After the Queen Metroid is defeated, the baby will accompany Samus if she uses a Teleport Station to travel elsewhere on SR388.

Metroid II: Return of Samus did not have such a feature, meaning that extensive backtracking would be required in order to return to past areas, and it was impossible to do so after the Queen Metroid battle.
